> what kind of type did you gave this field?
I gave him timestamp. so that i can better compare, add, substract and 
calculate wit date and time(s)
So in the BE the field has value timestamp.

I just want to change the appearance in BE record listing, so that the 
timestamp will be displayed as date(time)

Anyway, thanks for your hint I will check If I can get thet thing to work...
